why does the earth move sideways in the universe?

Answer 1

It is basically left over angular momentum from the formation of the solar system, much like the little whirlpool in a draining sink of water. The water in the sink seems perfectly still when you first pull the plug, but as the water moves toward the drain, the little bit of motion in it is magnified until there is a whirlpool right over the drain. In a similar way, as the interstellar cloud that collapsed to form the solar system collapsed, whatever little random motion it had was magnified until we have the planets orbiting quite fast around the Sun now.

Answer 2

The Earth is not moving sideways through the Universe. The Earth revolves around the Sun. Our solar system makes one revolution around our Milky Way galaxy every 250 million years. Our galaxy is also moving through the Universe. In fact in 10 billion more years our galaxy will collide with the Andromeda Galaxy.

Answer 3

the earth orbits around the sun, actually not call as moving sideway

Answer 4

there is no unliversally assigned direction in space, we visualize it traveling sideways, cause it's easier, it's just a matter of perspective

Besides, not all planets are on the same track, some planets rotate on a "ring" that might be at a near 90 degree angle to eachother - a solar system is like an atom, or atleast textbook representations of atoms

Answer 5

earth doesn't move sideway. It orbit around the sun.

Answer 6

earth is moving sideways in term of 4rth dimension which is time, its like a moving train, which travel straight and the cities it left behind is past. got me? lol

Answer 7

so the earth can be in his line of orbit.
